| Abstract: | We assessed the mitochondrial DNA sequence divergence of a 718 bp fragment of the control region and 1007 bp of the cytochrome b gene between two allopatric morphologically different subspecies of bluethroat ( Luscinia svecica ). None of the 17 total haplotypes was shared between L. s. namnetum and L. s. svecica . However, the mean distances between subspecies were very low for both fragments (0.00168 ± 0.00001 (mean ± SE) for the control region; 0.00306 ± 0.00016 for the cytochrome b gene). Only one substitution made the two subspecies genetically differentiated, highlighting their recent divergence. Interestingly, the control region was not more variable than the cytochrome b gene. |
